"looking for just some more thoughts recomendations or possibly just your experiences on props/
I have a 86 Sunrunner 210 with the Volvo aq151 and the 290sp drive 2:15 ratio. long hub.
the boat came with the wrong prop when I got it, it now has a left handed 14x19 aluminum (michigan)short hub prop, yes it has a short hub prop on the long hub shaft. at 3/4 throttle it will peg the tach at 6k. my max rpm should be 5500.
now I grabbed a nicely priced right handed michigan stainless SSV prop on ebay but it is a 14.5 x21 and it is a cupped prop (what ever this means) I figured this would be too much for it and I was looking for a 14x21 but this was cheap. and yep it is too much, it now will max out at 4800-5k rpm but is real slow out of the hole. my assumption is I need a 14x21 but what does Cupped blades do and does anyone have any experience with the design of the long and short hubed props? it looks like the short hubed prop has much less blade area then the long hubed props? so could a long hubbed 14x19 be ok even though what I have now is too small?"
